Certain Relations between Mutual Information and Fidelity of Statistical Estimation

Authors: Sudhakar Prasad

arXiv

I present several new relations between mutual information (MI) and statistical estimation error for a system that can be regarded simultaneously as a communication channel and as an estimator of an i...

Sequential design of computer experiments for the estimation of a probability of failure

Authors: Julien Bect, David Ginsbourger, Ling Li, Victor Picheny, Emmanuel Vazquez

arXiv

This paper deals with the problem of estimating the volume of the excursion set of a function $f:\mathbb{R}^d \to \mathbb{R}$ above a given threshold, under a probability measure on $\mathbb{R}^d$ tha...

Nonparametric Bayesian multiple testing for longitudinal performance stratification

Authors: James G. Scott

arXiv

This paper describes a framework for flexible multiple hypothesis testing of autoregressive time series. The modeling approach is Bayesian, though a blend of frequentist and Bayesian reasoning is used...

A model selection approach to genome wide association studies

Authors: Florian Frommlet, Felix Ruhaltinger, Piotr Twarog, Malgorzata Bogdan

arXiv

For the vast majority of genome wide association studies (GWAS) published so far, statistical analysis was performed by testing markers individually. In this article we present some elementary statist...

Posterior model probabilities computed from model-specific Gibbs output

Authors: Richard J. Barker, William A. Link

arXiv

Reversible jump Markov chain Monte Carlo (RJMCMC) extends ordinary MCMC methods for use in Bayesian multimodel inference. We show that RJMCMC can be implemented as Gibbs sampling with alternating upda...

Cosmic density field reconstruction from Ly-alpha forest data

Authors: Simona Gallerani, Francisco-Shu Kitaura, Andrea Ferrara

arXiv

We present a novel, fast method to recover the density field through the statistics of the transmitted flux in high redshift quasar absorption spectra. The proposed technique requires the computation...

Nonparametric Bayesian sparse factor models with application to gene expression modeling

Authors: David Knowles, Zoubin Ghahramani

arXiv

A nonparametric Bayesian extension of Factor Analysis (FA) is proposed where observed data $\mathbf{Y}$ is modeled as a linear superposition, $\mathbf{G}$, of a potentially infinite number of hidden f...

Synchronous bursts on scale-free neuronal networks with attractive and repulsive coupling

Authors: Qingyun Wang, Guanrong Chen, Matjaz Perc

arXiv

This paper investigates the dependence of synchronization transitions of bursting oscillations on the information transmission delay over scale-free neuronal networks with attractive and repulsive cou...

Frame theory in directional statistics

Authors: Martin Ehler, Jennifer Galanis

arXiv

Distinguishing between uniform and non-uniform sample distributions is a common problem in directional data analysis; however for many tests, non-uniform distributions exist that fail uniformity rejec...

Fast dynamics of odor rate coding in the insect antennal lobe

Authors: Martin Paul Nawrot, Sabine Krofczik, Farzad Farkhooi, Randolf Menzel

arXiv

Insects identify and evaluate behaviorally relevant odorants in complex natural scenes where odor concentrations and mixture composition can change rapidly. In the honeybee, a combinatorial code of ac...

Forecasting with Neural Networks: A comparative study using the data of emergency service

Authors: Muhammad Noor-Ul-Amin

arXiv

This is a case study discussing the supervised artificial neural network for the purpose of forecasting with comparison of the Box-Jenkins methodology by using the data of well known emergency service...

Sparse Choice Models

Authors: Vivek F. Farias, Srikanth Jagabathula, Devavrat Shah

arXiv

Choice models, which capture popular preferences over objects of interest, play a key role in making decisions whose eventual outcome is impacted by human choice behavior. In most scenarios, the choic...

Recording and Reproduction of Pattern Memory Trace in EEG by Direct Electrical Stimulation of Brain Cortex

Authors: A. G. Shapkin, M. V. Taborov, Yu. G. Shapkin

arXiv

This study demonstrates the capability of external signal recording into memory and the reproduction of memory trace of this pattern in EEG by direct AC electrical stimulation of rat cerebral cortex....
